DEVICE FOR REMOVING COKE FROM OVENS.

SPECIFICATION forming part of Letters Patent No. 428,466, dated May20,1890.

' Application filed August 15,1889. Serial No. 320,858. (No modelh Toall whom, it may concern:

Be it known that 1, WILLIAM H. DINSMORE, a citizen of the United States,and a resident of Connellsville, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inDevices for Removing Coke from Ovens; and I do hereby declare that thefollowingis a full, clear, and exact description of the invention,whichwill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to devices for removing coke from ovens; and itconsists in the construction and novel combination of parts, ashereinafter fully described and claimed.

The figure of the drawing is a view in perspective of the devicesuspended in an ovendoor ready for use, the oven proper being not shown,in order that the device itself may be more apparent.

Referring by letter to the accompanying drawing, A designates thedoor-frame, the side pieces of which are provided near their upper endsin their outer edges with downwardly and rearwardly inclined notches B0, arranged in the same horizontal plane, in which rests the removablehorizontal metal bar D, which is provided with a sliding hook E,which isslipped to place thereon, and may be moved on said bar D from jamb tojamb of the door when necessary. From the hook E depends a chain F,comprising several links, according to the size of the door in the ovenin which the coke-remover is used. From the chain F is suspended apulley-block or open metallic frame I, the whole device being of metalin order to resist the heatto which it must necessarily be subjectedwhen it is in use. The pulley G is journaled on a shaft H, having itsbearings in the arms of the pulley-block I. The upper end of thepulley-block I is provided with a swiveled eye L, to which the chain Fis connected.

The scraper or coke-removing device comprises a rod having anangularly-bent end or scraping-blade M at its front end, and a handpiece or ring N at its rear end, by which to manipulate it. Theclearing-rod, it will be seen, is supported in and guided by the sheaveof the pulley.

This means for suspending the scraper enables the operator to readilyhandle it, as he is relieved from much of the weight that has to beincurred in operating the ordinary scraper or coke-remover. It will alsobe seen that inasmuch as the shank of the scraper works within thegrooved pulley-wheel its inward and outward play is readily effected,the pulley, of course, greatly lessening the amount of friction. In thismanner the innermost portions of the oven may be reached, and to furtherincrease the efficiency of the device I have provided the constructionhereinbefore described, whereby the suspending device may be adjustedlaterally upon the transverse rod D, so as to reach the side portions ofthe oven; or, if preferred, instead of thus adjusting the devicelaterally for the purpose stated, the pulley-block I may be turned uponits swiveled eye Ii, thereby also enabling the inner end or blade of thescraper to reach the side portions of the oven.

There the doors are low in the ovens, the sheave or pulley can be hungto suit the workman as to height.

The expense attending the keeping in order of the ordinary scraper isconsiderable, and the labor of operating them is great.

The improved construction herein illustrated and described lessens boththe expense and the labor; hence its utility.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The herein-described device, consisting of a frame having the downwardlyand rearwardly inclined notches, a transverse rod having its ends seatedin said notches, a chain pendent from said rod and movable thereon, apulley-block swiveled to the lower end of said chain, so as to turnfreely in any direction, said pulley-block having mounted therein apulley-wheel, and a clearing-rod fitting in the groove of said wheel andguided thereby, said rod provided on its outer end with a hand piece orring and on its inner end with an angularly-bent scraping-blade,substantially as set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
